MACHINE FOR SETTING CAR-SPRINGS.

SPECIFICATION forming part Of Letters Patent No. 404,089, dated May 28, 1889.

Application file February 27, 1888. Serial No. 265,981. (ModeL) To all whom it may concern:

Be it known that 1, JAMES B. ILLINGS- WORTH, residing at Monroe, in the parish of Ouachita and State of Louisiana, have invented certain new and useful Improvements in Machines for Setting Car-Springs, of which the following is a specification.

My invention has for its object to provide a machine whereby the setting of locomotivesprings and passenger and other car springs is greatly facilitated, and wherebythe said setting may be accomplished in a positive and accurate manner.

My invention consists in certain novel features of construction and peculiar combination of parts, as will be hereinafter fully describedin the annexed specification, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of my improvement. Fig. 2 is a vertical longitudinal section thereof, and Fig. 3 is a top plan view of the same.

In the drawings, A denotes a rectangular beam mounted 011 suitable supports, a 64. Upon the upper face of the beam are secured longitudinal rack-bars B B, the teeth Z) Z) of which are inclined in opposite directions, as shown. Guided in longitudinal slots 0 0, formed by the side walls of the beam A and longitudinal angle-plates D, extending parallel with said beam and connected to the outer ends thereof, are two adjustable yokes, E E, which embrace the said beam and slide thereon, as shown.

Each of the yokes has the upper ends of its Vertical arms 6 extended above the beam, and has journaled therein, just above the rack-bar B, a transverse shaft, F, upon which is pivotally secured a pawl, f, which engages the racks B, for a purpose presently described. The upper ends of the arms e are also provided with perforations e., for the reception of removable pins 6 Projecting centrally up through an aperture, A, in the beam A is a spindle, 2, which has its lower end bifurcated, as at 2, and in said end is journaled a friction-roller, 10, as clearly shown in Fig. 2. In brackets G G de pending from the side plates, D, is journaled a transverse rock-shaft, II, which is provided with an inwardly-projecting arm, I, the outer end of which extends under and bears against the friction-roller 10. The outer extended end, 11, of the shaft has secured thereon the operating-lever 1, which is provided with a pawl, 0, adapted to engage a segmental rack, d, as clearly shown in the drawings. The upper projecting end of the spindle is provided with a shoulder upon which is seated a concave leaf-spring, 3, and resting upon the said upper end of the spindle, with its ends held in place by the yokes E, is the first (or pattern) leaf, 4, which has a desired onstated set.

In operation the yokes E are adjusted on the beam according to the length of the springs to be set, the pins e are withdrawn, and the set spring 4 is placed in position over the spindle, and within the projecting arms of the yokes E. The spring-leaf 5, which is first heated, is placed in its hot condition over the set spring, as shown by full lines in Fig. l; the pins e are then. inserted in their proper place. Power is then applied to the lever I, which causes the arm to press against the lower end of the spindle, the roller 10 reducing the friction 011 the fulcrum. This movement raises the spindle and the concave spring and forces the hot and cold leaves up into the position shown in dotted lines, Fig. 1, and compresses the said leaves together. The pawl on the lever engaging the rack holds the leaves in this position until they have been properly cooled for removal, The concave spring pressing against the springs when forced upward greatly facilitates the accuracy of the spring-leaf to be set.

To admit of setting springs of different widths and yet retain the two leaves in same parallel adjustment, I form the ends of the yoke-arms with beveled edges, as shown in Fig. 3, and over these edges I slide adjustable caps 7, which may be of various widths, thereby increasing or diminishing the transverse space between the yoke-arms. By forming the yokes with gravity-pawls adapted to engage the longitudinal racks the said yokes will be fixedly held in their adjusted position during the operation of setting the spring.

From the foregoing description, taken in connection with the drawings, the advantages of my improvement will readily appear. It will be seen that the same is simple in its operation, cheap as to cost of construction, and very effective and positive for its desired purpose.

Having thus described my invention, what I claim as new is 1. In a machine for setting car-springs, the

in adjusted positions, a vertically-movable spindle operating in the beam centrally between the yokes, and lever mechanism, substantially as shown, for raising the spindle and holding it in its raised position, as and for the purpose described.

3. A machine for setting car-springs, comprising a central beam, adjustable yokes arranged near the ends thereof and sliding on said beams, said .yokes adapted to hold the ends of the springs being set, a vertically movable spindle operating in the beam centrally between the yokes, a concave leaf-spring mounted on the upper end of said spindle, and means, substantially as shown and described, for raising the spindle, as and for the purpose described. v

4.. The combination, with the beam A and yokes mounted near the outer ends thereof for holding the ends of the springs, of a verticallymovable spindle operating in said beam centrally between the yokes, a concave leafspring mounted on the ends of the spindle, and means for raising said spindle, substantially as shown and described.

5. The vcombinatiomwith the beam and yokes mounted thereon adapted to hold the ends of the springs, of a vertically-movable spindle operating in the beam centrally between the yokes, said spindle provided with a frictionroller in its lower end, a rock-shaft mounted 7. In a machine for setting c'ar-springsthe,

yokes E, said yokes consisting of a body portion adapted to embrace the beam A, a gravity-pawl journaled between the vertical arms, near the upper end thereof, and a detachable rod or pin mounted in the outer ends of said arms, substantially as showmand for the purpose described.

8. In a machine for setting car-springs, the combination, with the yoke's E, adapted to encircle the beam A, the upper extended arms thereof provided with beveled edges, of the detachable sliding caps 7, substantially as and for the purpose'specified.
